Since a new compatible is needed to distinguish this second version of IOMMU hardware block from the first one, it is an opportunity to convert the binding to DT schema. version 6: - Remove #include - Remove pt_address_mask field - Only use once of_device_get_match_data - Return an error if ops don't match version 5: - Add internal ops inside the driver to be able to add variants. - Add support of v2 variant. - Stop using 'version' field - Use GENMASK macro version 4: - Add description for reg items - Remove useless interrupt-names properties - Add description for interrupts items - Remove interrupt-names properties from DST files version 3: - Rename compatible with soc prefix - Rebase on v5.12 tag version 2: - Fix iommu-cells typo in rk322x.dtsi - Change maintainer - Change reg maxItems - Add power-domains property Add IOMMU driver for rk356x This series adds the IOMMU driver for rk356x SoC.
